NS001 TMS: Site-Average Radiances for FIFE Ground Sites

39 FIFE ground measurement sites provide instrument-corrected spectral radiances across eight bands, extracted from NS001-TMS imagery. The data set contains a small number of observation dates per site, with multiple viewing angles from flight grid patterns. It includes geographic location, viewing, and solar angles for each observation, with radiances corrected using atmospheric aerosol optical thickness and gaseous absorption profiles.

Use Cases

• Canopy reflectance modeling studies based on multi-angle spectral radiance data.
• Validation of atmospheric correction algorithms using instrument-corrected radiance values.
• Analysis of surface temperature and solar irradiance using corrected thermal and visible/infrared channel data.
• Geospatial studies of vegetation using site-specific location and solar angle data.

Strengths

• Data includes instrument-corrected spectral radiances for eight distinct bands.
• Covers 39 distinct ground measurement sites with geographic and angular data.
• Atmospheric corrections applied using specific, cited algorithms (Fraser et al., 1989; Lowtran7).

Limitations

• Column names and exact row counts are unknown, limiting detailed structural understanding.
• License is ambiguously specified as 'other-license-specified' without further detail.
• There is a conflict in last updated dates: one source reports 1989-08-11, while others report 2026-04-09.
